My situation is somewhat similar to [this question](http://academia.stackexchange.com/questions/5997/what-to-do-with-an-accepted-phd-thesis-that-extensively-presents-quotes-as-parap?), but I'm the plagiarizer.

6 years ago I did my Master by coursework at university X, and wrote the Master thesis under supervision of a well-known prof. A. For many reasons that I don't want to list here, I did plagiarism. The content of my thesis is as follows:

    Part I: Back ground  
      ...
    Part II: Original Contribution

In the background part, I copied the whole chapter from text book T about algorithm S. Algorithm S is invented more than 50 years ago, several books describe it including the very well-known T. I didn't paraphrase at all, I started by citing T, and then copied the whole chapter word by word.

The contribution part is actually contribution. One year after I left the school, prof. A found another student to extend it and published the extension with me as the second author. (The paper included the algorithm and experiment in my thesis, but I didn't write a single word in the paper).

I have moved to university Y to do a PhD. I have published several papers in top conferences and have very good relationship with several well-known researchers. I want to advance in academic.

Will the Master thesis destroy my career in the future? If someone read my Master thesis, it is very easy to recognize, since the part from the text book is in perfect English, and the rest are **extremely** poor.

Can I contact the university to submit a revised Master thesis which re-described the algorithm S? This is the last thing I want to do.
